run integration-tests on tikv 6.5.8 without api-version = 2, got error

how to set the client to api-version = 1? use TransactionClient::new should use v1, but get the same error

[pingyu]

Currently integration tests are hard coded to v2.

Set clients to use API v1 by TransactionClient::new() or RawClient::new().

To address the error, you may also need to use a v1 client in clear_tikv().

I notice that and modify the TransactionClient::new_with_config to use Config::default() which will set Keyspace::Disable still get the same error. I guess somewhere(raw_delete_range) not properly handle this API version

I'm not familiar with tikv-rust-client, can you please check it? @pingyu

let client =
        TransactionClient::new_with_config(pd_addrs(), Config::default())

[pingyu]

I meant the error was raised from clear_tikv().

Change the Config::default().with_default_keyspace() in the following two lines to Config::default().

    let raw_client =
        RawClient::new_with_config(pd_addrs(), Config::default().with_default_keyspace())
...
...
    let txn_client =
        TransactionClient::new_with_config(pd_addrs(), Config::default().with_default_keyspace())

Thank you for your reply, after modifying clear_tikv(), the test cause TiKV v6.5.8 crash with errors😢 Do you have any suggestions？

Emmm... txn_client.unsafe_destroy_range(..) is not allowed in API v1.

Just comment out the the two lines. It's not necessary in API v1.

    let txn_client =
        TransactionClient::new_with_config(pd_addrs(), Config::default().with_default_keyspace())
            .await
            .unwrap();
    txn_client.unsafe_destroy_range(..).await.unwrap();

Thanks, comment out works. I ran the test many times and the following three tests have not passed, the txn_get_for_update sometimes not passed, is this expected？ @pingyu

[pingyu]

is this expected?

No. There seems to be bugs.
